I've tried building with/without -gcolumn-info and found almost no difference in compile time (+0.4%): $ /usr/bin/time clang -w -fno-builtin

...gdb testsuite to see whether that's a real problem. If that's a problem, it should show there (since GCC does not emit column info in dwarf, AFAIR). In any case, that would be a debugger issue.
